Kennebunk Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a proper look at what Kennebunk Beach has got cooking for us over the next couple of weeks. I’ll be straight with you – it’s a bit of a slow burn, but there’s a light at the end of the tunnel if you’re patient.

Right off the bat, the first week is pretty much a write-off. From Monday the 10th right through to the morning of Tuesday the 18th, it’s a long stretch of flat to tiny, messy waves that are just not worth paddling out for. The winds are mostly side-on or onshore, and the combined swell energy is weak, mostly well under 100. You’re looking at a long, quiet period there.

The first real glimmer of hope shows up on Wednesday morning, August 19th. Now, this is the standout of the whole outlook. We’ve got a bit of a pulse coming in – a clean 0.5m (2ft) swell from the SE, and get this, it’s *glassy*. The wind is a dead calm glass-off, which is a rare treat. The combined swell energy is moderate at 144, and the period is a solid 12 seconds, so it’s groundswell. This is a long period swell, meaning it’ll offer up some proper shape and a bit of push, perfect for the points and reefs rather than just closing out on the beach. It’s not big, but for a sheltered spot like Kennebunk, that glassy surface and that little bit of energy will make it feel much better than the number suggests. The water’s already a touch warmer than normal, sitting about 69°F, so you won’t need a thick suit.

After that little blip, it gets a bit messy again through the end of the week. Thursday the 20th and Friday the 21st see some bigger swell (up to 1.4m / 5ft) but the winds turn onshore and choppy, and that combined energy jumps up but the quality goes right out the window. It’s not worth getting excited about.

Rolling into the second week, we get another potential window. Saturday morning, August 22nd looks promising. It’s a smaller day, around 0.9m (3ft) from the SE, but the wind is clean and cross-offshore. The combined energy is a moderate 99. It won’t be a world-beater, but with a clean surface and a bit of shape, it’ll be a pleasant paddle.

Then Sunday morning, August 23rd, things get small again (0.4m / 1ft) but it’s *glassy* once more. The wind is glass, and the swell is from the ESE. It’s tiny, but if you’ve got a foamie, it might just be fun. The energy is low at 53.

Monday morning, August 24th offers up a cleaned-up 0.8m (3ft) swell with a moderate offshore wind from the ENE. It’ll be clean, but the period is short at 4 seconds, so it’ll lack any real punch. The combined energy is weak at 42.

Tuesday morning, August 25th is the last call for this outlook. We see 0.8m (3ft) from the SSE with clean cross-offshore winds. The combined swell energy is a moderate 98. It’s not a standout, but it’s a clean, fun-sized option to end the run.

So to wrap it up, the 19th of August is the clear hero of this forecast – that glassy, long-period morning is the only true golden window. The rest is a waiting game with a few small, clean windows for the patient ones. A blank run like this is pretty normal for this spot, so don’t stress it. Forecasts can always change.

Rusty.
